Hey, this is an amazing creation and i've tried to build the same.I've used same components, the only difference is that my pipe is 1.18" diameter. I've 340 turns on my secondary and i've tried between 2 and 8 turns for my primary, but this isn't working :(I've already tried to invert the primary after reading the comments, and i've tried with and without a breadboard ...My transistor heat a bit but it's not very hot.I need some help, thanks in advance !
